Precise measurements reveal that the exoplanets of the system discovered by ULiège researchers have remarkably similar densities, which provides new clues about their compositions.Credit: NASA/JPL-Caltech A new international…

A theory as to why the Sun's outer atmosphere differs in its chemical make-up from its inner layers has been confirmed by direct observation for the first time by scientists at UCL and the Italian Space Agency. The Sun's extremely hot…

ITHACA, N.Y. - Far below the gaseous atmospheric shroud on Saturn's largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Cornell University astronomers have estimated that sea to be at least 1,000-feet deep near its center -…

Results significantly narrow the range of possible places to find the hypothetical dark matter particles. The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter.…
